It's because a glider is shipped from the factory without an engine and rear ends Fitzgerald puts the engines transmissions and the rear ends in them....the engines are 12.7 liter Detroit diesels which were manufactured in 2004 so they were before the emissions so there is no regeneration no def to put in the truck you just put fuel in it and go.. .I had a Coronado from Fitzgerald it was never in the shop for being broke down or anything just in the shop to be greased and oil change...it's one of the best trucks have had..260 inch wheelbase too....I'm now stuck in a stinking Volvo I hate them things.
I used to have a picture of it on here but I can't find it no more
